OK Gu??mundu, thanks for putting me on to that wor-around.At first I was
getting errors though like "NFS over TCP not available from server ip" and
"mount call failed: 13". So with a little research I realised I had to do
a few extra things in addition to the "how-to" you linked to:
1. sudo apt-get install nfs-kernel-server
2. sudo vi /etc/exports
add the following:
/opt/ltsp/i386 192.168.100.1/24(rw,no_root_squash,async)
(change 192.168.100.1 to your own network)
3. sudo /etc/init.d/nfs-kernel-server restart
4. sudo exportfs -a
** For the above steps, these pages kinda helped:
http://ubuntuforums.org/showthread.php?t=249889
http://www.mail-archive.com/[EMAIL PROTECTED]/msg34378.html
** Now the how-to workaround you suggested will work, here it is for
reference:
5. sudo chroot /opt/ltsp/i386
6. Now edit /etc/default/ltsp-client-setup and change the value of the
root_write_method variable to use bind mounts instead of unionfs, it
should look like this afterwards:
root_write_method="bind_mounts"
7. Next, create the file /etc/initramfs-tools/conf.d/ltsp and add the
following line (set the value of the BOOT variable to nfs):
BOOT=nfs
8. Regenerate the initramfs:
update-initramfs -u
9. Hit CTRL-D to exit the chroot now. Make sure LTSP uses the new
initramfs to boot:
sudo ltsp-update-kernels
... all clients now boot, but I have to say I feel quite leary about this
workaround.
Is there somewhere I can report this as a bug?
Can anyone recommend any other solution?
Regards,
Tom Wolfe

I had the same problem some clients worked some didn't. Finally I tried
disabling NBD and enabling NFS as described here:
http://doc.ubuntu.com/edubuntu/edubuntu/handbook/C/customizing-thin-client.html
http://doc.ubuntu.com/edubuntu/edubuntu/handbook/C/customizing-thin-client.html
. I followed the instructions under "However, some people still want to use
NFS. Fortunately, it's easy to switch back to NFS, if it's so desired:".
Now my Dell OptiPlex GX1 client comes up, finally. I realize this is just a
workaround, there's something wrong in the NBD setup but I couldn't figure
it out. I'm using Ubuntu intrepid 8.10.

Hi again,
I'm now having problems with a few seemingly random clients that do not
boot up but fail at the following:

* Starting basic networking
* Starting kernel event manager
* Loading hardware drivers
* Loading kernel modules
* Loading manual drivers
* Setting up LTSP Client

I get the tty1 error on all machines even ones that succeed in booting up
(I'm using one of those right now in fact). But the ones that fail stop
with the message above (tty8). There doesn't seem to be any rhyme or
reason to which clients fail -- for example, a few Dell Optiplex GX115
work, a few don't; a few IBM Netvista work, a few don't.
Any advice?
Regards,
Tom Wolfe
